Patent number: 9030573Abstract: A camera system, image processing method and computer program stored on a computer readable medium for image processing. Long and short accumulation images with longer and shorter exposure times are respectively obtained from one field. First and second long accumulation evaluation values are computed from the long accumulation image. A short accumulation evaluation value is computed from the short accumulation image. A short accumulation target exposure time and short accumulation exposure control information are acquired from the short accumulation evaluation value and a first target level. A long accumulation evaluation value is acquired by synthesizing the first and second long accumulation evaluation values. Long accumulation exposure control information is acquired from the long accumulation evaluation value and a second target level. An image is generated from the long accumulation image and the short accumulation image.Type: GrantFiled: June 20, 2014Date of Patent: May 12, 2015Assignee: Sony CorporationInventors: Shingo Nagataki, Kenji Wajima, Hiroshi Yamamoto, Katsuhisa Shinmei

Patent number: 8970727Abstract: Disclosed herein is an image processing apparatus including a synthesizing processing section configured to synthesize a plurality of images taken at different exposure times wherein, in processing to synthesize the taken images, the synthesizing processing section acquires a taken-image blending ratio varying in accordance with components selected from the taken images and carries out a blending process on a blend area in which pixels of the taken images are to be blended by applying the blending ratio to the blend area.Type: GrantFiled: June 3, 2011Date of Patent: March 3, 2015Assignee: Sony CorporationInventors: Katsuhisa Shinmei, Hiroshi Yamamoto, Shingo Nagataki, Kenji Wajima
